在一项12万农村人群农药暴露与胎儿发育关系的3年回颐性调查中,我们发现某些农药的使用频率与不良妊娠结局存在一定的关系。本文报告了在该人群中验证以上结果的前瞻性流行病学研究。调查对象以49岁以下已婚未绝育的妇女为观察对象,其中在1988年元月1日至1989年12月31日出现妊娠结局的妇女,均要调查,每一孕次填调查表1张。调查内容包括孕期家中14种常用农药的使用情况(暴露指标)、妊娠结局(健康效应指标)和可能的混杂变量共42组。详见回顾性调查。数据处理用PEⅡ将数据输入IBM微机,用 In a 3-year survey of the relationship between pesticide exposure and fetal development in a population of 120,000 rural residents, we found that the frequency of use of certain pesticides was associated with adverse pregnancy outcomes. This article reports a prospective epidemiological study that validated the above results in this population. Subjects were surveyed under the age of 49 married women who have not been sterilized, of which women with pregnancy outcomes from January 1, 1988 to December 31, 1989 should be investigated. Each pregnancy should fill in a questionnaire . The survey included the use of 14 commonly used pesticides during pregnancy (exposure indicators), pregnancy outcomes (health effects indicators) and possible confounding variables in 42 groups.
